sides the aliphatic radicle with more than 8 carbon atoms, contain any further radicles, for example alkyl (including cycloalkyl) groups or aryl groups. They may be substituted, for example by further amino groups, by carboxyamido, carboxyl,-hydroxy1, aryl groups or halogen. The reaction may be effected by sulphonating the amines according to the usual methods for the preparation-of sulphamic acids. The usual sulphonating agents stronger than sulphuric acid, suchas oleum, sulphur trioxide, chloro or fluorosulphonic acid and sulphuryl chloride, if desired with the addition of substances removing water or hydrogen halides, such as organic or inorganic anhydrides as for example acetic or phosphoric anhydrides, may be employed. Mixtures of concentrated sulphuric acid with one or" more of the aforesaid anhydrides may also be employed. The co-employment of organic diluents inert to the sulphonating agents and amines under the conditions of working, such as diethyl ether, trichlorethylene, chloroform,

or especially of tertiary bases, such as trialkyl amines, pyridine, dimethylaniline and the like,

as such or in conjunction with the aforesaid solvents renders it possible to carry out the reaction with good yields and under especially mild conditions, such as below 80 C. so as to avoid losses by oxidation and decomposition. When employing sulphuryl chloride, the reaction products first formed, such as sulphamic chlorides or sulphamides, must be converted by' hydrolysis into the free acids or their salts. The amount of sulphonating agent in cases when the compound to be, sulphonated contains double linkages, hydroxyl groups or aromatic radicles shouldbe so selected that in so far as a sulphonation on a carbon or oxygen atom can take place under the reaction conditions chosen, a quantity of sulphonating agent is present which exceeds that reacting. with the said groups and suflices to form the sulphamic acid. If materials are to be sulphonated which contain unsaturated radicles the reaction is carried out with advantage in the presence of tertiary bases whereby the formation of such products as contain the sulphur connected to a carbon atom is suppressed; in this case the sulphonation can often be eil'ected in an advantageous manner by means of fluorosulphonic acid.

Products which are especially suitable as washing and cleansing agents are obtained when the high molecular fatty acids contained in vegetal are converted into amines, as for example by catalytic hydrogenation of acids or nitriles or by the Hofmann degradation, or when mineral acid esters of the alcohols obtainable from oils and fats by catalytic hydrogenation are converted into amines with ammonia or primary amines as for example cetyl iodide withammonia or .primary amines, or when acid amides which still contain primary or secondary amino groups, such as mono-palmitoyl ethylene diamine (R-CONH--C2H4-NH2), are converted into sulphamic acids in the manner described so that chains of from 10 to 18 carbon atoms are connected to a nitrogen atom. Compoundscontaining amino groups as well as acid amido groups are liable to be sulphonated on theamino groups when treated according to the present invention, 7 in so far as replaceable hydrogen is attached to the amino nitrogen atoms. The lower members of this series containing from 8 to. 12 carbon atoms yield excellent wetting and penetrating agents. Similar products may also be obtained by introducing high molecular organic radicles, as for example alkyl or cycloalkyl radicles, into the sulphamic acids of low molecular compounds as for example ethyl sulphamic acid.

The amines obtainable by reducing the acid amides of mixed aromatic-aliphatic carboxylic acids containing at least 8 carbon atoms in a non-aromatic chain as for example phenyl stearic acid QHOOH obtainable from benzene and oleic acid with the aid of aluminium chloride), of resinic and naphthenic acids and also those-of carboxylic acids from the destructive oxidation of paraflin wax with the aid of oxygen, nitrogen oxides or nitric fats, i. c. vegetable or animal solid or liquid fats,

acid give valuable products. The products obtained are valuable auxiliary agents for the industries which work up textiles and other fibrous materials as well as for all other purposes of industrial and daily use in which use is made oi alkylated naphthalene sulphonic acids, sulphonic acids from mineral oils, fatty acids, sulphonlc acids from acids oi vegetable and animal fats or oils or alcohols such as cetyl or dodecyl alcohols, or sulphuric esters of higher iatty alcohols, as for example of cetyl or dodecyl alcohols or the alcohols obtainable. by reducing the carboxyl groups of acids of vegetable or animal fats or oils or of the glycerides, with high molecular amines, such as dodecyl or pentadecyl amines, with hydroxyalkylamines, as for example ethanol, N-dodecyl N-ethanol or like amines, quaternary ammonium bases and their salts, such as trimethyl dodecyl ammonium sulphate or N-dimethyl N-ethanol N-dodecyl ammonium sulphate, or in conjunction with organic solvents, such as methyl cyclohexanol; tetrahydronaphthalene, ethylene glycol cresyl ether, trichlorethylene, or with protective colloids, such as glue, gelatine, starch, and vegetable mucilages, or with salts, such as sodium carbonate, sodium bicarbonate, waterglass, common salt, Glaubers salt, phosphates, such as meta or pyro sodium phosphate or bleaching agents, such as perborates, percarbonates, paratoluene sulpho-chloramide sodium salt and the like. The addition of the said agents depends on the purpose in view. Preparations which contain several of the said additions may frequently be employed with-advantage. The free sulphamic acids are not employed for neutral baths if these are to be heated to about their boiling point. or for baths containing tree acids; their salts with alkalies, such as alkali metals, ammonia or organic bases, such as mono-, dior trimethylamine, ethanolamine, pyridine and aniline may, however, be usefully applied with neutral baths.

The following examples will further illustrate the nature of this invention but the invention is not restricted to these examples. The parts are by weight.
